40 POINTS! NEED HELP ASAP! (More points on my other two posts, same question.) 1. This diagram represents a top-down view of an experiment on a table. The 428 g and 285 g masses are falling and are pulling the block. Draw an arrow to show which way the block will move. Do not interpret the size of the arrow; just draw the direction.

2. Draw additional masses to show how the block can be made to move toward point A. Be sure to draw the string and label the mass of the block. For full credit, draw the minimum number of blocks required to make the block move toward point A.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

In an experiment, how can i change human errors? be specific.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
